*s HUTTERi-WORKER;

SPECIFICATION forming part of Letters Patent No. 292,354, dated a Application filed August 31, 1883. (No model.) I

I0 all whom it may concern: I

Be it known that I, RONELLO F. Paa'rr, a citizen of the United States, residing at Everett, in the county of Middlesex and State of Mas witha handle, by whicheither can be rotated t.

On the outer endof both the spindle and the sleeve is a'toothedz segment,which gear respectivelywith a rackon a rod or bar, having a rack at its opposite end which gears with a pinion secured to the window-silh To this pinion is connected an arm or rod,which is attached or pivoted to the' lower part of the blind. By turning the hanindependently of the other.

dles and the spindle and sleeve on the inside,

either or both blinds can be opened or closed,; as desired. A clamping device is also pro-. vided on the inside, by which the blinds can.

be secured in any desired position,'either fully or partially closed or opened.

Referring, to the accompanying drawings, Figure l-is' an outside view'of a portion of .a

window and blinds with my invention applied. a Fig. 2 is a section on the line a: w of Fig.1.

Fig. 3'isa vertical section on the line y of Fig. 2; and Fig. 4 is a section, somewhat enlarged, on the linez z of Fig. 2.

A is the window-frame, B the window-sill,

and O O are the blinds, all of the usual construction.

Through the.wall O of the building, under the center of the window sill, is ahole, through which passes a tube or sleeve, D, set in proper bearings, so as to rotate freely, and passing through the sleeveD isa rod or spindle, E. I

On the inner end of the sleeve D,within the room, is fitteda handle,D, by which the sleeve D is turned in either direction, and on the end of the spindle E'is also a handle, E, for turning the said spindle.

-pinsl l on the bottom of-the blinds.

January 22, 1884.

To the handle E is attached'a slotted plate, 6, and to the handle D is attached a screw, 01, which passes through the slot in plate 6, and on the screw d is a thumb-nut, a, by means of which the handles D E can be locked in any desired position.

On the outer end of the sleeve D, outside the window, is secured a quadrantal toothed segment, G, and on the end of the spindle E is a similar toothed segment, F.

H and I are bars,which slide in opposite directions on a line parallel with the window-sill,

and are provided with teeth on theunderside of their inner ends, which engage with the toothedsegments F G, respectively. The bars H I, extending toward the ends of the sill, are bent upward, as shown in Fig. 1. and inward horizontally, as shown in Fig. 2, and are provided with teeth at their outer ends, which engage with pinions J K. The said pinions are pivoted to-the window-sill, and have arms L L attached to or forming a part of them, which arms'have holes at their outer ends fitting on Gaps or covers M are placed'over the gears F G. to pro- :tect the latterfrom snow and ice, and also serve to keep the gears in position. A plate, 13, is secured to the window-sill, andris turned up at the back, so as to hold the racks-in gear. with the-pinions. On the outside of the wall is a sliding collar, h, surrounding-the sleeve D, and

handles D, as Shown, it may be inserted in the wall'or the finish under the window, and the handles be secured by a thumb-screw.

When the blinds are required to be removed, they have simply to be lifted-offtheir hinges,

as they are not attached to any part of the device, the only connectionbeing the pin at the bottom passing through'the arm L.

It will-be seen that by simply turning the handles D E the segmental gears will cause the bars H I to turn the pinions J K, thus actuating the bars L L to open or close the blinds or hold them in any-position, as desired.

WVhat I claim as -myinvention is 1. A device foriop'er'ating outside blinds or IOO shutters from the} inside of a room, the same consisting'ofa sleeve and inclosed spindle pass ing throughthe wallor frame of a house,said

sleeve and spindle being each provided with a I plate 0, the screw (1, and thumb-nut a, sub- 10 toothed segment at their outer ends, in comstantially as and for the purpose set forth. bination with two separate toothed bars, each In testimony whereof Ihave signed my name operating a pinion and bar in connection with to this specification in the presence of two subtheblinds,whereby one or both blinds may be scribing witnesses.

separately operated, as desired, substantially as set forth. 6 l 2. The combinationmith the handles D E,

of the locking device consisting of the slotted ROXIZLLO F. PRATT. 'itnesses:
